Electron Coupled Oscillator (V.V) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12156
Indian Lab Suppliers supplies the Electron Coupled Oscillator (V.V) (Product ID: 12156) as part of its electronics engineering lab equipment range. It is a vacuum-valve training board showing how electron coupling isolates an oscillator from its load.
Quick Answer
A valve is mounted on the panel with its base wired internally, and a band switch selects different tuned circuits. Students first see how loading pulls and weakens a plain oscillator, then take the output through electron coupling into a separate tuned circuit and compare the result. In an electron-coupled oscillator the grids form the oscillator and the plate circuit is fed only by the electron stream, so load changes have little effect on frequency. An external regulated power supply is needed; the valve type and supply voltages are not stated, so please confirm them at quotation.
Key Specifications
| Parameter | Detail |
|---|---|
| Active device | One valve, base fixed on panel, wired internally |
| Tuned circuits | Selected by band switch |
| Experiments | Effect of loading on an oscillator; reducing it by electron coupling |
| Connections | 4 mm terminals; stackable spring-loaded patch cords, 0.5 m |
| Also required | IC regulated power supply |
Where This Is Used
Used in valve and communication electronics courses with the Twin-Tee Oscillator (V.V) (Product ID: 12157). Valve anode supplies are at dangerous voltages and valves run hot, so work under supervision and switch off before touching the board.
